This was super helpful, thank you! I used the trial key this time to be sure it worked, but will be more than happy to purchase the service when I need it next :)

Tried other sites, but they did not work. This one worked like a charm, wish I had found this one first.

thank you for the free trial!! I think the printer companies should give low income customers the reset key free!! It took me a few tries to get this to work, but was successful. You saved my day!!
